I just think it's a bad slippery slope to be on.
Ice Rager sees no play. Next expansion they introduce Chaos Rager, 7/2 creature.
That doesn't see play, they make a 8/2 God Rager.
And so on. Or even worse examples:
King of the Arena: 5 mana 6/5 Taunt
Priest of Elune: 5 mana 5/4 Heal for 4 Health
etc.
I agree with you.
To me the issue was never whether it was a super big problem or an almost unnoticeable problem, but an indication of what Blizzard's thought process could be going forward. I just didn't find their arguments about it that compelling to agree with them.
